Does the Mirena IUD Cause Hair Loss and What Can You Do About It?
Summary
Yes—about 1 %–6 % of Mirena users report noticeable hair shedding, usually within three months of insertion. The hormone levonorgestrel can briefly tip the scalp into a “telogen” (resting) phase, but most cases stabilize or reverse within a year. Persistent, patchy, or rapidly worsening loss needs medical review to rule out thyroid, iron, or autoimmune problems and to discuss keeping versus removing the IUD.
Is Mirena really linked to hair loss, and how common is it?
Mirena releases the progestin levonorgestrel, which can trigger a temporary telogen effluvium in a small subset of users. According to post-marketing data, 4,400 hair-loss complaints were filed among roughly 100 million Mirena devices worldwide. The team at Eureka Health notes that most cases are self-limiting.
- Hair shedding peaks around 8–16 weeksMost users who experience Mirena-related shedding notice it during the second or third hair-growth cycle after insertion.
- Only a minority see true thinningRandomized trials report hair loss in 1 %–6 % of users compared with 0.6 % in copper-IUD users.
- The hormone involved is levonorgestrelHigh local levels can transiently lower estrogen on the scalp, shortening the anagen (growth) phase.
- Removal is rarely requiredLess than 0.5 % of users ultimately choose to remove Mirena solely for hair concerns.
- New Zealand pharmacovigilance found alopecia in only 0.33 % of Mirena usersAnalysis of 15,697 levonorgestrel-IUD users in the Intensive Medicines Monitoring Programme recorded a cumulative alopecia incidence of 0.33 % (95 % CI 0.07–0.95). (PubMed)
- Package insert classifies hair loss as an ‘uncommon’ (<5 %) side effectMirena’s prescribing information, as summarized by Healthline, lists alopecia among adverse events reported in fewer than 5 % of clinical-trial participants. (Healthline)
Which hair-loss patterns after Mirena insertion should make you see a clinician immediately?
Most shedding is diffuse, but certain patterns hint at another problem. “Patchy or scarred areas are not typical for Mirena and deserve prompt dermatology referral,” says Sina Hartung, MMSC-BMI.
- Bald spots or broken hairsAlopecia areata, tinea capitis, or trichotillomania must be ruled out.
- More than 100–150 hairs lost per day for 8 weeksSustained high counts suggest severe telogen effluvium or early female-pattern loss.
- Scalp itching, redness, or scaleInflammatory conditions like psoriasis or seborrheic dermatitis may be the real culprit.
- Concurrent weight gain, fatigue, or cold intoleranceThese systemic signs point toward thyroid dysfunction, not Mirena itself.
- Ferritin below 30 ng/mLIron deficiency can amplify shedding and needs treatment regardless of IUD status.
- Patchy bald spots reported 6 weeks after insertionA case in O&G Magazine details a 43-year-old who developed alopecia areata six weeks after Mirena placement; hair regrew once the IUD was removed, making any localized bald patches a red-flag for specialist referral. (O&G)
- True Mirena-related alopecia is rare at 0.33%In a safety analysis of over 17,000 users, researchers found a cumulative alopecia incidence of just 0.33% (95% CI 0.07–0.95); persistent shedding beyond normal daily loss should therefore prompt a clinician check to rule out other causes.

What at-home steps can slow mild Mirena-related hair thinning?
Support the hair cycle while your body adjusts. “Think of it as giving follicles the raw materials and a calm scalp environment while hormones rebalance,” advises the team at Eureka Health.
- Ensure 20–25 g of protein per mealHair is 90 % keratin; inadequate amino acids prolong the resting phase.
- Aim for ferritin above 50 ng/mLStudies show regrowth accelerates once iron stores surpass this threshold.
- Use 2 % pyrithione zinc shampoo twice weeklyKeeping the scalp micro-inflammation low helps follicles stay active.
- Limit high-heat styling to under 180 °C (356 °F)Thermal damage causes shaft breakage mistaken for hormonal thinning.
- Track daily shedding in a 60-second comb testA simple count gives an objective trend you can share with your clinician.
- Up to 16 % of Mirena users report noticeable sheddingPatient surveys summarized by hair-researchers found about 16 % of women experienced significant hair loss, underscoring why proactive scalp care matters during the first months of use. (Neofollics)
- Saw palmetto or inositol can blunt androgenic impactAn OB/GYN specializing in hormonal IUDs recommends adding these supplements to help neutralize the DHT-like activity of levonorgestrel that can miniaturize follicles. (IG)
Which lab tests and prescription options do doctors consider if hair loss follows Mirena?
Blood work clarifies whether hormones or nutrients are driving the shed. “Targeted testing avoids guessing and prevents unnecessary IUD removal,” notes Sina Hartung, MMSC-BMI.
- TSH and free T4 screen for thyroid diseaseUp to 8 % of postpartum women with IUDs develop thyroiditis presenting as hair loss.
- Serum ferritin and complete blood countIron-deficient women are twice as likely to report shedding.
- Total testosterone and DHEA-S if acne is presentAndrogen excess can cause female-pattern loss that mimics Mirena shedding.
- Topical 5 % minoxidil remains first-lineRandomized studies show 40 % greater density at six months, even when the IUD stays in.
- Low-dose oral spironolactone (25–100 mg)Some clinicians use anti-androgen therapy if labs confirm elevated androgens.
- Include zinc, B12, folate and magnesium panelsProgestins may deplete these micronutrients, so checking and correcting levels can halt telogen effluvium without removing the IUD. (Instagram)
- Autoimmune and inflammatory screens help exclude alopecia areataA case report used CBC, vitamin B12, CRP, ESR and auto-antibody panels to rule out other causes before deciding on device removal. (O&G)
When should you consider keeping, replacing, or removing the Mirena IUD?
Decision-making balances contraceptive needs against hair concerns. “Most patients prefer a three-month wait-and-see unless shedding is severe or emotionally distressing,” says the team at Eureka Health.
- Transient telogen effluvium often resolves by month 1280 % of affected users report stabilization without removal in observational cohorts.
- Switching to Kyleena lowers hormone exposure by 45 %A smaller-dose levonorgestrel IUD may ease hair complaints while preserving contraception.
- Copper IUD is hormone-free but can increase bleedingHeavier periods may worsen iron-related shedding if stores are low.
- Systemic hormonal birth control can worsen sheddingPills with high androgenicity (e.g., levonorgestrel or norgestrel) are not ideal substitutes.
- Remove immediately if emotional distress outweighs benefitsMental-health impact is a valid medical reason for device removal.
- Alopecia reported in up to 16 % of Mirena usersClinical trials list hair loss in fewer than 5 % of women, but a Finnish post-marketing study cited by researchers documented hair loss in nearly 16 %, signaling wide individual variability. (Healthline)
- Hair regrowth observed after device removal in case reportsOne published case showed shedding stopped and new growth appeared once the Mirena was removed, illustrating that hair loss can be reversible when conservative measures fail. (O&G Mag)

Frequently Asked Questions
How long after Mirena insertion does hair loss usually start?
Most people notice increased shedding between 8 and 12 weeks, aligning with the hair-growth cycle length.
Will removing Mirena immediately stop the hair loss?
Shedding often continues for 3–6 months after removal because follicles already in the resting phase still fall out.
Can I use over-the-counter biotin to help?
Unless you have a lab-confirmed biotin deficiency (rare), extra supplements have not proven to speed regrowth and may interfere with thyroid tests.
Does Mirena cause permanent baldness?
Typical Mirena-related telogen effluvium is temporary; permanent loss is rare and usually indicates an unrelated condition like female-pattern alopecia.
Is hair loss more common with the second Mirena than the first?
Current data do not show higher rates with replacement devices, but individual sensitivity can vary.
Can stress from the IUD procedure itself trigger shedding?
Yes—any significant physical or emotional stress can precipitate telogen effluvium about three months later, regardless of hormones.
Should I avoid hair coloring during the shedding phase?
Gentle coloring is safe, but harsh bleaching can worsen breakage; consider demi-permanent dyes and deep conditioning.
How do I know if my ferritin is ‘low’ for hair health?
Many dermatologists aim for at least 50 ng/mL, even though labs list 10–15 ng/mL as ‘normal’ for general health.
Is Kyleena less likely to cause hair loss than Mirena?
Kyleena releases about half the daily levonorgestrel dose; some sensitive users report fewer hair issues, but head-to-head studies are limited.
Can Eureka order a topical minoxidil prescription for me?
Yes—if your profile fits guideline criteria, the AI submits a draft prescription for a physician on the platform to review and approve.
